Abstract

PURPOSE:To obtain an inexpensive electronic typewriter equipped with a memory prevented from the invasion of external noise by providing a metal connection arm to an FDD and arranging the lead wire of the FDD in the connection arm. CONSTITUTION:An FDD l equipped with a floppy disk driver and a lead wire 3 constitutes an FDD unit along with a chassis 5, a panel 6 and a housing 7. The FDD l, the chassis 5 and the panel 6 are assembled so as not to apply unreasonable stress to the FDD 1. A connection arm 4 is a recessed metal jig having positioning pawls 4a, 4b provided to the front and rear parts thereof. The connection arm is excellent in strength because of its recessed structure and has a structure holding the lead wire 3 of the FDD between the arm 4 and a sheet 8 within a recessed part 4c. The connection arm 4 is mounted on the FDD unit 10 by screws in such a state that the pawl 4a of the front part of the connection arm 4 is engaged with the hook 7a of the housing 7.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic typewriter with memory, in which a floppy disk drive is externally attached to the typewriter body.

BACKGROUND OF THE INVENTION In recent years, with the spread of electronic devices such as electronic typewriters with memory and their increasing sophistication, electronic typewriters have become equipped with floppy disk drives (hereinafter referred to as FDD) in order to store increasing amounts of text on floppy disks. abbreviated)
There is a tendency to expand the system by installing .

A conventional electronic typewriter will be described below with reference to FIGS. 4(a) and 4(b).

In the figure, 1 is an FDD equipped with a mounting bracket 1a, and 2 is an FDDI controller board. Further, 3 is a lead wire of the FDD which has connectors 3a and 3b at both ends.

A method for installing the FDD 1 in a conventional electronic typewriter constructed as described above will be described below.

From the back of the typewriter body to the body, mounting bracket 1
By tightening a with a screw (not shown in the diagram),
Attach FDDl.

FDDI and controller board 2 are connected to FDD lead wire 3
The lead wire 3 of the FDD is disconnected and the show 1
- Store it inside the typewriter body so that there is no damage.

Problems to be Solved by the Invention However, the conventional configuration described above requires space for mounting the FDDI in the typewriter body, which poses a major problem when miniaturizing electronic typewriters. For this reason, small electronic typewriters have an external FD.
Many wear D. However, in such a configuration, the FDD and lead wires are normally connected to the electronic typewriter separately, and the lead wires are exposed to the outside. For this reason, it is necessary to use shielded cables for node wires that are not affected by external noise, and to use high-strength connectors when connecting lead wires to connectors installed outside electronic typewriters, which is expensive. The problem was that it turned into something.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an inexpensive electronic typewriter with a memory that prevents the intrusion of external noise.

Means for Solving the Problems In order to achieve the above object, the present invention provides an FDD with a metal coupling arm, and arranges a lead wire of the FDD within the coupling arm.

Effect: With the above configuration, the lead wire of the FDD is held inside the metal coupling arm, so the lead wire is shielded from external electromagnetic waves. Therefore, the external FDD and the main body of the electronic typewriter are not electrically connected or subjected to noise interference through a single lead wire.

Embodiment FIGS. 1(a) and 1(b) are block diagrams of F'DD used in an electronic typewriter in an embodiment of the present invention. In the figure, 4 is a metal coupling arm. .

The FDDI with the FDD lead wire 3 attached is attached to the chassis 5. The panel 6 and the housing 7 constitute an FDD unit l-10. FDDI and chassis 5 and panel 6 are FD
It is assembled so that no excessive stress is applied to the DI.

The connecting arm 4 is a concave metal fitting having positioning claws 4a and 4b at the front and rear. The concave structure provides excellent strength, and the FDD lead wire 3 is sandwiched between the concave portion 4c and the sheet 8.

The coupling arm 4 is attached to the FDD unit 1-10 by tightening screws with the claw 4a at the front of the coupling arm 4 and the hook 7a of the casing 7 engaged.

The attachment of the external floppy disk drive unit of this embodiment constructed as described above to the typewriter body will be described below. FIG. 2 is a front view showing the FDD unit 10 attached to the typewriter main body by the connecting arm 4, and FIG. 3 is a bottom view of the main part.

In FIG. 3, one of the hooks 4 of the coupling arm 4 is inserted into the square hole 9b on the groove 9a of the typewriter body to position it in the groove for attaching the coupling arm 4 provided on the base of the system main body.
The FDD unit 10 is attached to the groove 9a of the typewriter body by tightening two screws in the hole 9c.

Since the lead wire 3 of the FDD is held inside the coupling arm 4 as described above (not shown in the figure), the connector 3b of the lead wire 3 of the FDD shown in FIG. 1 is connected to the FDD controller board 2. Just by doing this, FDD unit 1
The electrical connection between 0 and the typewriter body is completed.

According to the present invention, when connecting the lead wires 3 of the FDD, there are no troubles such as lead wires being caught or cut, no expensive special parts are required, and inexpensive lead wires and connectors can be used as in the past.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the FD
The D unit is externally attached to the system main body by a connecting arm, and since this connecting arm has a concave structure and has positioning claws at both ends, it has excellent strength and workability during installation. In addition, the lead wire is placed inside the coupling arm, which solves the problem of lead wire wiring processing, has a shielding effect from external noise, and is cost-effective compared to using a special shielded cable. We can provide electronic typewriters with memory.
