Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a flat cable attachment structure for a printer, and particularly to an attachment structure between a connector and a flat cable.

[Prior Art] A conventional printer flat cable mounting structure has a structure as shown in FIG. That is, the connector 2 is fixed on the circuit board 1 so that the flat cable insertion port 2a is oriented horizontally. The flat cable insertion port 2a of the connector 2 has a printing head (not shown) at one end.
The connector insertion portion 3a at the other end of the flat cable 3 to which is fixed is detachably inserted.

[Problems to be solved by the invention] In order to attach the flat cable 3 to the connector 2, it is necessary to grasp both sides of the connector insertion part with your fingers and insert it, which has the disadvantage that it is difficult to insert it because the film has a flexible structure. Furthermore, a board for the connector was prepared separately from the flat cable, and a means for electrically connecting the flat cable was also required.

The purpose of the present invention is to provide a printer flat cable mounting structure that does not require wasted space, does not require a means for connecting the connector board and the flat cable, and allows the flat cable to be easily attached and detached. .

[Means for Solving the Problems] The configuration of the present invention for solving the problems of the above-mentioned prior art will be explained with reference to FIGS. 1 and 2, which correspond to embodiments. The circuit board 14 is the mechanical frame 13
is located below. A flat cable insertion port of the connector 15 is arranged on the mechanical frame 13 side. The connector insertion portion 10a side of the flat cable 10 is bent at a right angle,
A cable fixer 12 is fixed to the bent portion 10b of the flat cable 10.

[Example] An example of the present invention will be described below with reference to FIGS. 1 and 2. A printing head 11 is fixed to one end of the flat cable 10, and a connector insertion portion 10a at the other end of the flat cable 10 is fixed to one end of the flat cable 10.
The side is bent at a right angle to form a bent portion 10b. A cable fixer 12 is fixed to this bent portion 10b. The cable fixer 12 has a vertical fixing part 12a and a horizontal fixing part 12b to which the flat cable 10 is fixed.
A holding part 12c extends upward from the horizontal fixing part 12b, and a hook part 12d projects horizontally from the holding part 12c. The horizontal fixing portion 12b provides rigidity and prevents the flat cable 10 from floating up.

A circuit board 14 to which electronic components are attached is arranged below a mechanical frame 13 that supports a mechanical part. As a result, the external size of the printer can be reduced, there is no need for a means to electrically connect the connector board and the circuit board, and the wiring to the function key, display element, sensor, print head motor, etc. can be kept as short as possible. can.

The connector 1 is placed on the circuit board 14 with the flat cable insertion port (not shown) facing upward.
5 is fixed. Furthermore, on the connector 15,
a cable guide 16 that covers the connector 15 and guides the flat cable 10 to the connector 15;
is installed. Also this cable guide 1
Mechanical frame 13 corresponding to the guide hole 16a of No. 6
A hole 13a is formed in the portion shown in FIG.

Next, the effect will be explained. Holding the holding part 12c of the cable fixer 12 with your fingers, insert the connector insertion part 10a of the flat cable 10 into the cable guide 16 through the hole 13a of the mechanical frame 13. In this case, it will be easier to enter if the horizontal fixing part 12b is pressed from above. As a result, the connector insertion portion 10a of the flat cable 10 is connected to the connector 1.
5. Further, the flat cable 10 can be easily removed from the connector 15 by hooking a finger on the hook portion 12d and pulling the cable fixer 12 upward.

In this way, since the flat cable 10 can be attached and detached from the connector 15 from above,
There is no need for wasted space around the connector 15, and miniaturization can be achieved. Also flat cable 10
The connector insertion portion 10a side is fixed to the vertical fixing portion 12a and horizontal fixing portion 12b of the cable fixer 12, so the vertical fixing portion 12a gives rigidity to the flat cable 10, and the horizontal fixing portion 12b This prevents the flat cable 10 from floating up.

Note that the cable guide 16 does not need to be provided, but if the cable guide 16 is provided, the flat cable 10 can be easily attached and detached, and even if the distance between the mechanical frame 13 and the connector 15 is large, the flat cable 10 can be attached and detached.

[Effects of the invention] As is clear from the above explanation, according to the invention, the rotating board is arranged below the mechanical frame,
The connector has a flat cable insertion port arranged on the mechanical frame side, the connector insertion part side of the flat cable is bent at a right angle, and a cable fixer is fixed to the bent part of the flat cable. This eliminates the need for wasted space around the connector, allowing for miniaturization. Further, the cable fixer provides rigidity to the flat cable and prevents the flat cable from floating up.
