Abstract

PURPOSE:To eliminate the damage to a guide rail directly participated in printing accuracy and securing stable printing quality while attaining the effective utilization of a carriage moving space at the time of transport, by providing the mount means of a receiving box so as to attach the same to an upper cover. CONSTITUTION:A carriage 12 is equipped with a type wheel 12a, a hammer 12b and a cassette ribbon 12c and an upper cover 17 is attached to a main body case 10 in a freely revolvable manner. The type wheel 12a or the like are received in a receiving box 18 so as to be made freely detachable to the hooks 17c, 17d of the upper cover 17. This receiving box 18 is arranged so as to be received in the space occupied by the reciprocal movement of the carriage 12 when the upper cover 17 is rotated to the direction shown by the arrow 19 to be closed. As mentioned above, because the mount means of the receiving box 18 is provided to be attached to the upper cover 17, the damage to guide rails 13, 14 is eliminated and stable printing quality is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an electronic typewriter that utilizes the space in which a carriage moves back and forth to provide an accessory case.

(b) Prior Art Conventionally, Japanese Patent Laid-Open No. 59-93369 has proposed a system for storing accessory parts by utilizing the space in which the carriage reciprocates. As shown in Fig. 5, this is an electronic typewriter in which a carriage 4 carrying a type wheel, a hammer, a cassette ribbon, etc. prints on paper as it moves back and forth along a platen 6 holding paper. , the accessory parts 7 are housed in the space A occupied by the carriage 4 reciprocating during the printing operation.

As shown in FIG. 6, this accessory part 7 includes a protrusion 7a,
7b and spring members sa and sb, and these protrusions i78, 7
It is removably attached to two guide rails 5a and 5b that guide the carriage 4 when it reciprocates in the left-right direction by spring members sa and sb.

(C) Problems to be Solved by the Invention In the conventional example described above, the accessory part 7 is attached to and detached from two guide rails that control the reciprocating movement of the carriage, which is directly related to print quality.

For this reason, lubricants such as grease that are applied to the guide rail to smooth the reciprocating movement of the carriage may be removed when attaching or detaching non-essential parts, or the guide rail may be damaged by attaching or detaching it. There was a risk of

If the guide rail is damaged in this manner, the carriage drive system is overloaded, causing erroneous printing.

Furthermore, when a fairly heavy accessory such as a power supply device is attached, the guide rail may be deformed, impairing smooth movement of the carriage. For this reason, the guide rail must be set to have enough rigidity to withstand the overload than the load of the carriage alone.
This led to an increase in costs.

The present invention solves the problems of the above-mentioned conventional example.

(d) Means for Solving the Problems The present invention provides an upper cover rotatably attached to the main body case so as to cover the moving space of the carriage, and a By providing an electronic typewriter with a storage box removably attached to the top cover so that it can be stored in the
This solves the problems of the conventional example described above.

(e) Examples The present invention will be described in detail below based on the drawings.

FIG. 1 is a perspective view of an electronic typewriter showing an embodiment of the present invention. 10 is the main case, 11 is the main case 1
This is the keyboard provided on the front of the 0. 12 is a type wheel 12a, a printer 12b, and a cassette ribbon 12.
This is a carriage carrying items such as c.

13 and 14 are guide rails that guide the carriage 12 to move left and right, 15 is a platen, and 16 is a paper pail.

Reference numeral 17 denotes an upper cover, which is rotatably attached to the main body case 10 via a hinge portion 17a. Inner surface 17b facing carriage 12 when upper cover 17 is closed
7 pieces 17c as shown in Figures 2 and 3,
17d is provided to vertically protrude from the inner surface 17b.

Reference numeral 18 denotes a storage box for storing type wheels and the like, and is detachably attached to seven hooks 17c and 17d of the upper cover 17. As shown in FIG. 4, the side surface of the storage box 18 is provided with a locking portion 18a into which the hook 17c is locked and a relief hole 18b at the tip of the hook 17c. This storage box 18 is arranged so as to be stored in the space occupied by the reciprocating movement of the carriage 12 when the upper cover 17 is rotated in the direction of the arrow 19 and closed.

In addition, when closing the upper cover 17, it is necessary to move the carriage 12 to a predetermined position, for example, to the right end as shown in FIG.

Further, this storage box 18 is provided with a storage partition 18c for arranging and storing a plurality of type wheels in all or part of its interior, so that a large number of type wheels can be stored in an orderly manner. It is configured. The type wheel in electronic typewriters has several types of type sizes and styles, such as pyro, elite, and micro, and types are grouped according to the language used, such as English, German, and French. For this reason, it is usually necessary to carry many type wheels, but in this embodiment, it is possible to carry many type wheels together with the electronic typewriter body.

In addition, when using an electronic typewriter, remove the top cover 17.
The storage box 18 is to be used after being rotated upward and opened, and the storage box 18 is removed from the upper cover 17. Also,
In this embodiment, the storage box 18 is
Although a hook is used as a means for attaching to the device, any appropriate attachment means such as a rubber band or a screw may be selected, and the present invention is not limited to this.

(f) Effects of the Invention According to the present invention, since the storage box attachment means is provided on the upper cover and attached, there is no danger to the guide rail which is directly related to printing accuracy as in the conventional case. , stable print quality and effective use of carriage movement space when portable.

Additionally, multiple type wheels can be stored neatly and carried along with the typewriter.
