Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in the technical field of time recorders, and more specifically, when a push button for attendance and attendance selection and setting mode selection provided on the upper surface of a time recorder in a row is pressed. The present invention relates to an improvement of a push button switch device for a time recorder configured so that the head of the push button is illuminated by an LED (light emitting diode) to clearly indicate an ON state, and the operation of the time recorder is performed in the operation mode of the push button that is illuminated when pressed. Is.

[0002]

2. Description of the Related Art When a push-button for attendance / leaving selection / setting mode selection provided on the upper surface of a time recorder is pressed to turn on the switch, the head of the push button is illuminated by an LED and the operation mode of the time recorder is changed to the operation mode of the push-button. As a push-button switch device for a time recorder that is configured to automatically switch, there is a push-button switch device described in Japanese Patent Application No. 2-20313 (Japanese Utility Model Publication No. 3-113471) previously proposed by the present applicant.

The above-mentioned conventional push button switch device for a time recorder has a push button vertically movably fitted inside a vertically long fitting hole formed on the upper surface of the recorder, and is bent downward by being pushed by the lower end portion of the push button. , The pressure lever protruding from the lower side of the LED turns on the switch attached to the printed circuit board.
And a support piece configured to light,
In addition, by making the support piece and the connecting portion of the mounting plate thin, it is possible to elastically return upward while pushing up the push button due to the elasticity of the material when the downward bent support piece is released. I am configuring.

[0004]

Therefore, in the above-mentioned conventional device, the push button is fitted into the fitting hole on the upper surface of the recorder in advance, while the switch, the LED, and the support piece are assembled on the printed circuit board side to separate them. After that, the position of the push button and the support piece was adjusted on the line, but this position adjustment is very troublesome and troublesome, and since the block inspection and the main assembly inspection are required, the assembly work is complicated. There was a problem.

In addition, there are problems that the number of parts is large and the entire apparatus becomes large, and that maintenance is troublesome, and that the push button falls out from the fitting hole during transportation of the block product. There was also.

The technical problem of the present invention is that a push button switch device for a time recorder can be easily manufactured with a smaller number of parts than conventional ones at low cost, and the entire device can be manufactured. Provided is a push button switch device for a time recorder, which is configured to be integrally assembled, and further has a function that the pushed push button can be surely returned to its original position and that the push button can be prevented from slipping out during transportation. That is.

[0007]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows.

A plurality of pushbuttons for selecting attendance / leaving and selecting a setting mode are provided side by side on the upper surface of the recorder body. When these pushbuttons are pushed, the LED emits light to illuminate the head of the pushbutton, and the time recorder. In the time recorder configured to switch the operation of to the operation mode selected by this push button,

(1) A fulcrum portion is provided on one side of each of the push buttons, and when the fulcrum portion is pressed by the head of the push button, the entire push button is rotated downward about the fulcrum portion. And a switch for the LED that is turned on by being pushed by the lower end pressing portion of the downwardly rotating push button, while being rotatably supported by the holder-side support portion in which is inserted.

(2) One side surface of the holder is constructed by using a printed circuit board, and the LED is mounted on the inner side surface of the printed circuit board.
And attach a switch that turns this LED on and off.

(3) On the upper surface of the holder, a spring plate portion formed at the tip is connected to the back surface of the push button so that the push button pressed downward can be returned to the original position by elastic force and rotated. Attach the configured elastic plate.

(4) A plurality of fitting holes are formed on the upper surface of the horizontally long holder at intervals in a row, and push buttons fitted in the fitting holes are formed on both sides of each of these fitting holes. A support part for rotatably supporting a shaft-shaped fulcrum part provided on both sides of the holder is provided, and the head of each push button corresponding to each of the above push buttons is provided on the inner side surface of the printed circuit board mounted on one side of this holder. LED for making the unit illuminate, and a switch for LED that is turned on by being pushed by the lower end pressing portion of the push-pushed push button, and each spring plate thinly formed in a comb shape on the upper surface of the holder. Attach an elastic plate made of plastic or metal, whose tip is integrally connected to the back surface of each push button.

(5) A plurality of push buttons for attendance / leaving selection and setting mode selection are provided side by side on the front side of the card pocket into which the time card is inserted.

[0014]

The means described in (1) to (5) above operates as follows.

According to the means described in the above (1), when the push button is pushed, the whole push button has a structure in which the lower end pushing portion of the push button directly pushes the LED switch. Since the switch can be turned on and off properly and the push button itself directly turns the switch on and off, the number of parts is small, and the troublesome work such as position adjustment is unnecessary. The work is very simple, the manufacturing cost can be reduced, and the entire device can be made relatively small.

According to the means described in (2) above, since the printed circuit board on which the LED and the switch are mounted is attached to the holder itself in which the push button is fitted, the push button, the LED and the switch are integrated around the holder. It is possible to greatly simplify the assembling work and the adjusting work.

According to the means described in the above (3), when the push button is pushed by the finger, the push button rotates while the spring plate of the elastic plate bends downward and the switch is turned on. When the button is released, the elastic restoring action of the spring plate pushes the push button back to its original position and makes a return rotation. Therefore, the switch can be reliably returned to the OFF state, and the push button is supported by this spring plate during transport. Can be prevented from falling off the holder side.

According to the means described in the above (4), a plurality of push buttons are fitted on the upper surface of the horizontally long holder so that the fulcrum portion of each push button is supported by the support portion, while the rear surface of each push button is supported. An elastic plate integrally formed with a substantially comb-shaped spring plate is attached to the upper surface of the holder so as to elastically support each push button, and a plurality of LEDs and switches on the side surface of the holder. If a printed circuit board mounted with is mounted, a switch device incorporating a plurality of push-buttons for attendance and attendance selection and setting mode selection in a horizontal row can be assembled very easily and accurately without adjusting the position of each part. You can

According to the means described in (5) above, since the pushbuttons of the switch device assembled as described above are provided in a row in a row on the front surface of the card pocket, the operation of these pushbuttons can be inserted into and removed from the card pocket. This makes it possible to perform extremely smoothly without being disturbed by time cards or setting cards.

As described above, the above-mentioned technical problems can be solved by the above-mentioned means, and the problems of the above-mentioned conventional techniques can be solved.
