There is provided a printing method using a first motor that applies a driving force for rotating a roll body around which a printing medium is wound, a second motor that applies a driving force for intermittently driving a transport driving roller that transports the printing medium, and a print head that intermittently ejects ink onto the printing medium alternately with the driving of the second motor. The printing method includes driving the first motor such that tension applied to the printing medium is constant during at least a part of a period in which the second motor is driven and stopping the driving of the first motor during at least a part of a period in which the driving of the second motor is stopped.

In a photo film carrier for use with a photographic printer, a winding device includes a rotatable winder shaft for photo film. A feeding path introduces the photo film to the winder shaft. A leading end guide plate is curved in an arc shape at a predetermined interval L to the winder shaft, for receiving a leading end of the photo film having reached the winder shaft from the feeding path, to guide the photo film toward the winder shaft in an arc shape. A tightening guide mechanism is curved in an arc shape, for tightly fitting a leading end on the winder shaft by pressing the photo film from the feeding path, to prevent the leading end from being loose at the winder shaft when a second turn portion of the photo film comes to contact the leading end after substantially one rotation of the leading end.

An electrical connector for connecting to a terminal post. The electrical connector includes a housing body, a contact and a locking release member. The housing body includes a post receiving passage for receiving the terminal post therein. The contact is provided in the post receiving passage and is positioned about the circumference of the post receiving passage. The contact will make an electrical engagement with a terminal post inserted into the post receiving passage regardless of the orientation of the terminal post with respect to the contact. The locking release member is moveably mounted to the housing body and is moveable between a first position and a second position. The locking release member cooperates with a locking spring member. The locking spring member has a locking section which cooperates with a recess of the terminal post when the locking release member is in the first position.

A steering device comprises an upper steering shaft, a lower steering shaft for transmitting rotations of the upper steering shaft to a steering gear, an engaging projection provided on a fitted-in portion of the upper shaft, an engaging groove provided on a fitted-in portion of the lower shaft for engaging with the engaging projection with a clearance of a rotational direction and a rotational direction biasing member, provided on the fitted-in portion, for giving a biasing force of a rotational direction between the upper and lower steering shafts.

An operator cab 53, which is mounted rotatable on the vehicle body 51 of a hydraulic mini-shovel 50, comprises a cab box 1, a door 2, upper and lower link members 3 and 4, a slide member 6, a closed door lock 7, an opened door lock 9 and a handle 13. The cab box 1 has an internal cab room 1a and an entrance 15, which leads into the cab room 1a. The door 2 closes and opens the entrance 15 when it is moved forward and rearward, respectively. The upper and lower link members 3 and 4 have fixed ends 3a and 4a, each of which is connected pivotally to the cab box 1, and moving ends 3b and 4b, each of which is connected pivotally to the front end of the door 2. The slide member 6 is connected pivotally to the rear end of the door 2 so as to swing freely and slides along a slide rail 5, which is provided externally on the cab box 1. The closed door lock 7, which is provided at the front end of the door 2, engages with a closed door striker 8, which is provided on the cab box 1, when the door 2 is closed. The opened door lock 9, which is provided at the front end of the door 2, engages with an opened door striker 10, which is provided on the cab box 1, when the door 2 is opened. The handle 13 is provided at the front end of the door 2 and interlocked with the closed door lock 7 and the opened door lock 9.
