Problems solved by technology

[0008] Mounting a fan and a filter for capturing ink mist on a printer requires space to arrange them, making it difficult to downsize the device
In addition, a driving source for driving the fan is required, and there is a problem that the manufacturing cost of the device increases.

[0042] Hereinafter, an embodiment of a printer 1 to which the present invention is applied will be described with reference to the drawings.

[0043] (the whole frame)

[0044] figure 1 It is an external perspective view of the printer 1 according to the first embodiment viewed from the direction of the paper discharge port 8 (referred to as the front). The printer 1 has a printer main body 2 and a reversing unit 3 . The printer main body 2 has a rectangular parallelepiped shape that is long in the printer width direction X as a whole. The reversing unit 3 is mounted to a recess 4 provided at a central portion of the rear surface of the printer main body portion 2 . The reversing unit 3 is a unit for reversing the printing paper P from the front to the back.

Abstract

Airborne ink mist is prevented from sticking to the detector part of a paper detector disposed on a carriage without using a configuration for capturing the ink mist. A printer has a conveyance path that conveys paper past the print position of a printhead; a carriage that carries the printhead; and a carriage moving mechanism that moves the carriage bidirectionally on the transverse axis of the printer. A paper detector and a shutter that opens and closes the detection part of the paper detector are disposed on the carriage. When the carriage moves to one end of the range of carriage movement, a shutter operating member disposed on a second side frame facing the carriage contacts the shutter and moves the shutter from its open position or closed position to the other position.

Description

technical field [0001] The present invention relates to a printer having a paper detector mounted on a carriage and a paper position detection method of the printer. Background technique [0002] In the serial printer, the printing paper is conveyed along a conveyance path passing the printing position of the printing head, and the planned printing start position on the printing paper is positioned as the printing position. Thereafter, the printing operation and the paper feeding operation are repeated and alternately performed. The printing operation is an operation of printing while moving the printing head along the width direction of the conveying path perpendicular to the conveying direction of the printing paper at the printing position, The paper feeding operation is an operation of feeding printing paper by a predetermined paper feeding amount at a time along the feeding path. The print head is mounted on a carriage, and the carriage reciprocates in the width direct...
