Abstract

PURPOSE:To enable to obtain a sound-insulating effect and inspectability, by a method wherein a main body of a printer is provided with an opening part for fitting and detaching a tractor mechanism, and a cover provided with a tiltable part at the rear edge is rotatably connected to the opening part to cover the latter. CONSTITUTION:When printing on an ordinary paper, a transparent tiltable part 12 of the cover 9 is leveled, and the opening part 8 is closed by the entire part of the cover 9 to insulate printing sounds. When printing on a perforated paper, the tiltable part 12 is raised, a cover 23 for the tractor mechanism 22 is set into a fitting space, and the part 12 is set against front faces of the cover 23 to insulate sounds. When inspecting the interior of the main body 1 of the printer, the cover 9 is opened by rotating with hinges 19, 20 as a center, and an arm 18 is engaged to a pawl 21 to maintain the opened condition. Accordingly, effective insulation of printing sounds is achieved by the cover, and the cover can be maintained in the opened condition without detaching it when inspecting the interior, thereby enhancing convenience in handling.

Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a printer.

[Technical background of the invention and its problems]

Typically, printers include a cover that covers the printhead tab latin. The vapor will be taken in and taken out from the rear edge of this cover, but it is desirable to extend the cover as far back as possible to prevent printing noise from being emitted to the outside. On the other hand, there are several tractor mechanisms selectively installed in the printer body for feeding sprocket paper, but these tractor mechanisms require a large installation space and interfere with a portion of the cover mentioned above.

For this reason, there are two types of covers that can be used depending on the type of use, with and without the tractor machine 41 yen attached, but since the number of 1ilX items increases, the cost increases, and the operation and storage of different uses is also difficult. It's inconvenient. First, the cover mounting structure is a snap-in type, so when inspecting the inside, the removed cover must be placed in a different position, making it inconvenient to handle if there is no space on the desk. ing.

[Purpose of the invention]

This invention was made in consideration of the two issues, and it is possible to obtain an effective print sound insulation effect with a single cover even in different usage patterns, and it is possible to maintain the cover in an open state without removing it during internal inspection. The purpose is to provide a printer that is easy to handle.

[Summary of the invention]

In this invention, both rear sides of the cover are rotatably attached to the printer body, and when inspecting the inside, the cover is opened and work is done from the front.When using plain paper, the entire cover has a large area to insulate the sound of writing. In the case where a tractor mechanism is attached, the undulating part provided on a part of the rear edge of the cover is raised rearward to expand the mounting space for the tractor mechanism, and this raised undulating part also provides a sound insulation effect. During internal inspection, the cover is held in the fully open state by the locking part provided on the printer body, and if an external force is applied to the cover from the fully open position in the fully open direction, the cover is separated from the printer body at the hinge. It is also constructed so that internal inspections can be carried out more easily with a larger work space.

[Embodiments of the invention]

An embodiment of this invention will be described based on the drawings.

A printer main body (1) is formed by assembling two upper and lower cases (2) and (3). At the rear of the printer main body (1), there are provided levers (5) and (6) located within the tractor mechanism mounting space (4). Although these operating levers (5) and (6) are not shown, they are used to suspend the feed roller and paper pail row 2 from the platen by 1 ton of liquid.

Next, the printer main body (1) is formed with a horizontally elongated holding part (7) through which paper can be taken in and taken out, and a wide opening part (8). Cuckoo (9) covering the entire area of this opening (8)
are the same as the main cover (if), the transparent monitoring cover aυ, the transparent undulating portion 0→, and the side cover Q3. The undulating portions (other than the ridges are connected to each other, and the undulating portions are held by the side cover Q1 by hinges and can be raised and lowered rearward and upwardly.Side cover O) and the upper case (2)
The shaft of the platen is protruded, and a semicircular hole 00η for entering a dial (IC9) is formed at the protruding end.Furthermore, the side cover α1 has an arm Q signal extending rearward. These arm θ whips are formed with hinges α made of pins that protrude laterally, and the printer body has a hinge wing shaped to elastically fit the hinge (IC) from below, and arm OP9 has elastic springs. Actively engaged +) f?
A claw eυ which is li is formed.

In such a 4"1' configuration, when printing on plain paper, as shown in Figures 1 and 2, the undulating part 04 is laid down and the opening (8) is closed with the entire cover (9). to block the printing sound.When using sprocket paper, see Figures 3 and 4.
As shown in the figure, raise the undulating part vr and widen the space.
Set the tractor mechanism (44 tractor cuckoo) in the 4-ket tractor mechanism mounting space (4).
The first one is placed against the front of the tractor cuckoo ball. This undulating portion u4 hides the rear portion of the opening (8) and also has a shielding effect. The printing condition of both plain paper and sprocket paper can be seen through the transparent monitoring cover 〇υ, but the edge of the undulating SUa on the vertical side of the 9th edge and the joining edge with < 19 can be seen to check the printing condition!
Since it is located outside the Iet, it will not be difficult to see.

When inspecting the inside of the printer body (1), as shown in Fig.
At this time, as shown in FIGS. 1 and 8, the arm θ is elastically engaged with the claw eυ, so that the cup can be maintained in the fully open state. About this time y1. 〃Tame et al. 6
Furthermore, when a force is applied to the cover (9) in the opening direction, the seventh
As shown in the figure, the arm Q smoke comes into contact with the edge of the opening 11 (8) and the lever action removes the hinge (11) from the hinge holder, so the working space is extremely wide when making repairs. Become.

[Effects of Departure 11] This invention is configured as shown in -L9E, so in the case of printing on plain paper, the entire cover has a large area to insulate the printed matter from sound, and a tractor mechanism is attached (in the case of 1J). , the space for the tractor mechanism is expanded by raising the undulations, and the raised undulations also provide a sound insulation effect, which makes it possible to avoid the need for a heavy cover. Furthermore, by providing an inspection area on the printer, it is possible to keep the cover open for internal inspections, etc., and there is no need to place the cover in another place, so it can be used on a narrow desk. As you work, you can also choose how to use the printer by removing the cover hinge and the printer body hinge, and removing the cover from the opening to widen the work space and perform internal inspections and other tasks. It has the following effects:
