Abstract

PURPOSE:To set an ink ribbon easily without making hands dirty by manipulating each elastic ribbon support member which is elastically engaged with each cassette arm portion thereby to move from the position to guide the ink ribbon to the position of the ribbon cassette. CONSTITUTION:An elastic ribbon holding member 3 is formed by an elastic plate and positioned at a position (1) where it is engaged with cassette arm portions 4, 5 except when an ink ribbon is set. When the ink ribbon is set, each elastic ribbon holding member 3 is moved to the vicinity of a printing part 7. In this case, first, each elastic ribbon holding member 3 is moved upwards and detached from the cassette arm portions 4, 5. Thereafter, ends 3a, 3b of each elastic ribbon holding member 3 are pressed by hands, so that the holing member 3 in moved. If the ends 3a, 3b are released from the pressuring force of the hands after the elastic ribbon holding member 3 is moved, clamp portions 3c, 3d of the elastic ribbon holding member 3 are elastically engaged with an ink ribbon 2, thereby clamping the ink ribbon. Accordingly, the ribbon can be set to the printing part 7 easily by holding the elastic ribbon holding members 3 by hands without making the hands dirty.

Description

[Detailed Description of the Invention] [Summary] Regarding a ribbon setting method for a stationary ribbon cassette used in a printer device, the purpose of this invention is to improve the setting performance by making it possible to set the ink ribbon without holding it by hand. A pair of cassette arms for feeding out and retracting the stored ink ribbon protruding from both sides of the ribbon cassette, and a pair of cassette arms for guiding the ink ribbon by elastically engaging with each of the cassette arms so as to be movable in the protruding direction. a position where the elastic ribbon holding member is elastically engaged with the ink ribbon exposed between each of the cassette arms (4, 5) after the elastic ribbon holding member is moved from each of the cassette arms in the respective protruding directions and removed; After that, each elastic ribbon holding member is held by hand to set the ribbon in the printing section.

(Industrial Application Field) The present invention relates to a ribbon setting method for a stationary ribbon cassette used in a printer device.

This type of stationary ribbon cassette is equipped with a pair of cassette arms for feeding out and retracting the stored ink ribbon that protrude from both sides, and the stored ink and ribbon are fed out from the cassette arm for feeding out. The cassette is then pulled into the cassette from the cassette arm. Printing is performed using an ink ribbon exposed to the outside between the two cassette parts.

When setting the ink ribbon of this stationary ribbon cassette in the printing section, if you hold the exposed part of the ink ribbon with your hand, your hands will get dirty.

Therefore, it is necessary to take precautions to keep your hands clean.

[Conventional technology]

For this reason, in the past, the shape of the ribbon guide provided in the printing section was designed to make it easier to set the ribbon, thereby reducing the amount of time it took to grasp the ribbon by hand.

[Problem to be solved by the invention]

However, in the above-mentioned conventional method, the ink ribbon must be grasped by hand, and the time required to grasp the ribbon varies depending on the individual operator, so the hands are never completely clean.

SUMMARY OF THE INVENTION An object of the present invention is to provide a ribbon setting method for a stationary ribbon cassette, which can improve the setting property by allowing the ink ribbon to be set without being held by hand.

[Means to solve the problem]

FIG. 1 is an explanatory diagram of the principle of the present invention. In the figure, ▪ indicates a stationary ribbon cassette for storing an ink ribbon 2, and 3 indicates a pair of elastic ribbon holding members.

The stationary ribbon cassette l is equipped with a cassette arm 4 for feeding out the ink ribbon protruding from one side, and a cassette arm 5 for drawing in the ink ribbon protruding from the other side. The ink ribbon 2 is fed out from the cassette arm 4 and drawn into the cassette from the cassette arm 4. The figure shows an example in which the ink ribbon 2 is endless, and the ink ribbon 6 is provided inside the cassette. This is the shaft of the ink ribbon drive roller.

The elastic ribbon holding member 3 guides the ink ribbon 2 by elastically engaging each cassette arm 4.degree. 5 so as to be movable in the respective projecting directions (in the vertical direction in FIG. 1).

When setting the ribbon, each elastic ribbon holding member 3 is moved upward from the position (3) where it engages with each cassette arm 4.5 and guides the ink ribbon 2, and the respective cassette arm 4.
5, move the ribbon to the position (3) where it elastically engages with the exposed portion of the ink ribbon 2, and then hold each elastic ribbon holding member 3 by hand and insert the ribbon into the printing section 7. conduct.

[Effect]

In this way, when setting the ribbon, each elastic ribbon holding member 3 at the position ■ is held by hand, but at the position 200, each elastic ribbon holding member 3 is elastically engaged with the ink ribbon 2. Because of this, the ribbon can be easily set without getting one's hands dirty, and the ease of setting the ribbon can be improved. In this case, the position of ■ is the printing part 7.
It is desirable that the location be close to .

〔Example〕

The present invention will now be described in detail with reference to FIGS. 2 to 5.

Figure 2 is an explanatory diagram of the structure of a stationary ribbon cassette (Figure 2 (
a) is a plan view, and FIG. 2 is a side view), in which the same reference numerals are used for the same members as in FIG. 1.

The elastic ribbon holding member 3 is formed by molding an elastic plate into the shape shown in FIG. This elastic ribbon holding member 3 is positioned at the position (3) where it engages with the cassette arms 4 and 5, as shown by the solid line in FIG. 2, except when the ribbon is inserted. FIG. 4(a) shows an example of the holding state of the cassette arm 5 in this state (cross-sectional view taken along the line A-A in FIG. 2(a)). The cassette arm 5 is elastically engaged with the cassette arm 5 and is movable in the direction in which the cassette arm 5 protrudes (in the direction perpendicular to the paper plane of FIG. 4).

When setting the ribbon, move each elastic ribbon holding member 3 to the position indicated by the chain line in FIG.
, ). In this case, first move each elastic ribbon holding member 3 upward in FIG. 2(a) to separate it from each cassette arm 4, 5, and then move it as indicated by the arrow in FIG. 2(a). During these movements, the ends 3a and 3b of each elastic ribbon holding member 3 are pressed and moved by hand in the direction shown by the arrow in FIG. 4(a). It's easy. Then, each elastic ribbon holding member 3
When the end portions 3a and 3b are released from the position indicated by the chain line, the clamp portions 3c and 3d of each elastic ribbon holding member 3 move to the position indicated by the chain line, and the clamp portions 3c and 3d of each elastic ribbon holding member 3 move to the position indicated by the chain line.
to be elastically engaged and clamped. Therefore, in this state, each elastic ribbon holding member 3 can be held in the hand to easily set the ribbon in the printing section 7 without getting the hands dirty. In other words, the centripetality of the ribbon is improved. FIG. 5 shows a state in which the ink ribbon 3 is set in the printing section 7 in this manner.

In FIG. 5, 11 is a print head, 12 is a mask, 1
3 is an indicator, 14 is a ribbon guide, and print head 11. Indicator 13. The ribbon guide 14 is attached to a carrier (not shown), and the mask 12 is fixed to the indicator 13.

After the ribbon setting is completed, each elastic ribbon holding member 3 is returned to the position indicated by the solid line in FIG. 2 in the reverse order as described above, and printing is performed in this state. The ink ribbon traveling during the printing operation is guided by each elastic ribbon holding member 3 in each cassette arm 4.5.

〔Effect of the invention〕

As described above, according to the present invention, when setting the ribbon, each elastic ribbon support member 3 is operated to be moved from the position where it elastically engages with each cassette arm and guides the ink ribbon to the ribbon center position. By doing so, it is possible to easily set the ribbon without getting your hands dirty, and ribbon centability is improved.
