Problems solved by technology

[0015] Also, since there are many parts to be mounted, a predetermined mounting area is required on the printed circuit board to be mounted, and the miniaturization of the printed circuit board itself is limited, and because the vibrator of the RC oscillation circuit 101 to be mounted has a certain thickness, so It is impossible to try to realize the miniaturization and thinning of the shell of the remote control transmitter, and the design of the shell will also be limited

Embodiment Construction

[0052] Below, use figure 1 and figure 2 The microcomputer 1 of the present invention will be described. figure 1 It is a block diagram showing main parts of the remote control transmitter 10 in which the microcomputer 1 is installed.

[0053] The action of remote control transmitter 10 is to utilize microcomputer 1 to control, as figure 1 As shown, a keyboard switch 12 composed of a plurality of keys 11, 11... is connected to the microcomputer 1. The keyboard switch 12 is an output lead pattern 13A drawn from the input and output signal terminals of KI / O1 to KI / O6 of the microcomputer 1 and an input lead pattern 13B drawn from the input signal terminals of KI0 and even KI3, which are insulated from each other and arranged in a matrix On a printed wiring board (not shown), a pair of switch electrodes are respectively connected to the output lead pattern 13A and the input lead pattern 13B intersecting at crossing positions to form the key 11 . The pair of switch electrod...

Abstract

The invention provides a microcomputer manufacturing remote control transmitter (10) corresponding to various controlled equipment in a short time. The solve method is to set up programming ROM (3) which can overwrite and store utility programs, RC tank circuits (6), and an energizing circuit (7) of light items which drives and controls infrared light items (16) in the microcomputer (1) handled the movement of remote control transmitter (10), and to make the main units of the remote control transmitters (10) of different specifications joint use one IC array.

Description

technical field [0001] The present invention relates to a microcomputer for controlling the action of a remote control transmitter. More specifically, it relates to a microcomputer with a built-in programmable ROM (Programmable Read Only Memory). The programmable ROM can be programmed on site to control the action of a remote control transmitter. s application. Background technique [0002] A conventional remote control transmitter (Patent Document 1) of a controlled device such as a remote control television receiver is provided with a keyboard switch composed of a plurality of keys, and once one of the keys is input and operated, the control corresponding to the operated key is included. The infrared control signal of the command will emit light from the infrared light-emitting element, and the controlled device that receives the infrared control signal will perform an action according to the control command. [0003] [Patent Document 1] Patent No. 3153084 (column 3, colu...
