Abstract

PURPOSE:To facilitate fitting and detaching a printing head and enhance assemblability and operability, by a method wherein a wiring extended from a printing head is connected to a connector substrate, and a connector fitted with the substrate is so constructed that it can be made slidable. CONSTITUTION:Lead wires extended from a driving part of the printing head 8 are connected to the connector substrate 9, which is provided with a fitting surface 11 to be fitted to the connector 10. On the other hand, a head base 12 is provided with a hole 13 into which the fitting surface 11 of the substrate 9 is inserted, and the connector 10 is slidably fitted by small screw or the like to a bottom surface of the hole 13 through a lower part of the head base 12. The connector 10 is provided with freedom in vertical directions A, forward and backward directions B and lateral directions C. A flat cable 14 is extended from the connector 10 to a controlling circuit or the like.

Description

[Detailed description of the invention] The present invention relates to a lead wire from a print head drive unit.

This invention relates to a printer that has an improved connection structure with a flat cable that transmits printing commands from a control circuit or the like.

FIG. 1 shows an example of a conventional cable coupling structure to a print head. In FIG. 1, a print head 1 is placed on a head support stand 3 that is slidably provided in a direction parallel to the axis of the platen 2, and has the function of printing on the printing surface of the platen 2. Lead wires 4 taken out from the drive section of the print head 1 are bundled and attached to a connector 6. On the other hand, a connector 7 is disposed on the head support base 3 to which a flat cable 6 for transmitting printing commands from a control circuit or the like is attached. In this configuration, when the print head 1 is mounted on the head support stand 3, the connector 5 and the connector 7 are fitted to form an electrical connection. That is, by this fitting, a printing command from a control circuit or the like is transmitted to the drive section of the print head 1 through the flat cable 6,
Printing operations are performed.

In the above conventional configuration, when the connector 5 to which the lead wire 4 from the print head 1 is attached is fitted into the connector 7 of the head support 3, the connector 7 of the head support 3 is connected to the head support 3. Since the fitting part 7a of the connector 7 is placed on either the left or right side of the connector 7,
It is necessary to pull out a long lead wire 4 from the print head 1, hold the connector 6 of the print head 1 with your hand, and turn the fitting portion 5a of the connector 5 sideways so that they face each other to fit together. The reason why the connector 7 is provided on the side of the head support stand 3 is that the head 1 must print characters from one end of the platen 2 to the other, so the length of the head support stand 3 should be as narrow as possible. This is because there is no space to provide the connector 7 on the top surface. Therefore, when attaching and detaching the print head, the assemblability and operability are poor, which becomes particularly noticeable when the printer becomes smaller and the space in which the head support base 3 can move becomes narrower.

The present invention solves the above-mentioned drawbacks and provides a printer having a structure in which the print head can be easily attached and detached, and is easy to assemble and operate.

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 2 is an exploded perspective view showing the main parts of this embodiment, and FIG. 3 is a sectional view of the main parts.

In the drawing, 8 is a print head, and 9 is a connector board to which lead wires from a drive section (not shown) of the print head 8 are wired. This connector board 9 is attached to the print head 8 in a fixed state. The connector board 9 also has a mating surface 1 that is mated to the connector 10.
1 is provided. On the other hand, a hole 13 into which the fitting surface 11 of the connector board 9 is inserted is formed in the head support base 12.
A connector 10 is slidably attached to the bottom of the hole 13 from the bottom of the head support 12 with screws or the like. Here, the connector 10 has degrees of freedom in the up-down direction A2, the front-back direction B, and the left-right direction C, as shown by the arrows. Note that the flat cable 14 extends from this connector 10 to a control circuit (not shown) or the like.

In the above embodiment, the wiring of the print head 8 is connected to the connector board 9 fixed to the print head 8, and the connector 10 provided on the head support stand 12 and to which the =1 connector board 9 is fitted is connected to the top, bottom, left and right. 2, so that when the print head 8 is mounted on the head support 12, the fitting surface 11 of the connector board of the print head 8 and the connector of the head support 2 10 can be easily fitted together, improving work efficiency and positioning the head 8.

As is clear from the above embodiments, according to the present invention, the print head can be easily attached and detached, which improves assembly and operability, greatly contributes to improved maintenance, and has great practical effects. .
