Specific implementation mode

With reference to specific embodiments and the drawings, the utility model is described in further detail, elaborates in the following description More details are in order to fully understand the utility model, but the utility model obviously can be different from what this was described with a variety of Other manner is implemented, and those skilled in the art can be without prejudice to the utility model connotation according to practical application feelings Condition makees similar popularization, deduces, therefore should not limit the scope of protection of the utility model with the content of this specific embodiment.

It should be noted that Fig. 1 to Figure 15 only as an example, its not be according to equal proportion condition draw, and And it should not be construed as limiting in this, as the protection domain to the utility model actual requirement.

As shown in Figure 1, 2, 3, in one embodiment of the utility model, printing equipment 900 includes door closure component 1 and seat Body component 2, pedestal component 2 include door with the cavity 2010 with opening for accommodating print media 910, door closure component 1 Lid ontology 10, door body 10 are pivotally connected on pedestal component 2, and conjunction is covered with rotation or opens cavity 2010.Printing is situated between Matter 910 (being shown in Fig. 9,11) can be printing paper roll made of paper material, can also be by other kinds of printed material (such as the material of printable photograph) is made.Door body 10 can also be by other means connected on pedestal component 2, unlimited In pivot connection.

Continue to refer to figure 1,3, when door body 10 is under lid conjunction state, door closure component 1, which is snapped, is connected to pedestal On component 2, cavity 2010 is in pent state at this time.The concrete form snapped connection is described further below.

With continued reference to Fig. 2,3, pedestal component 2 includes switch module 21, and after pressing switch module 21, above-mentioned buckle connects It connects and is opened, door closure component 1 is bounced by the elastic mechanism inside printing equipment 900, and door body 10 becomes opening state, at this time Cavity 2010 is also turned on, and print media 910 can be put into cavity 2010 by user.The concrete structure and door closure group of switch module 21 The principle that part 1 is bounced is described further below.

After print media 910 is put into cavity 2010, user can manually close the lid of door closure component 1 on pedestal component 2, come Closed cavity 2010.Later, the other assemblies in pedestal component 2, such as print components 22 print unit 223, then start work Make, with the type information on print media 910.The concrete structure of print components 22 is described further below.

When needing to be replaced print media 910, user's pressable switch module 21 is again turned on cavity 2010, And cavity 2010 is stretched into manually take out print media 910 and replace.In general, working as print media 910, such as printing paper It rolls up, after a part of being used up, the position being located in cavity 2010 can be deep, is not easy to take.In addition, door closure component 1 is beaten After opening, the paper knife 203 of printing equipment 900 is directly exposed to outer, the easy hand to user when user takes printing paper roll It damages.

Therefore, print media 910 is picked and placeed in order to facilitate user, in one embodiment of the utility model, printing equipment 900 further include dielectric support 11, and dielectric support 11 can exist independently of door body 10.Specifically, dielectric support 11 can It is actively set to inside cavity 2010, and is suitable for holding up print media 910 out of cavity 2010.For example, dielectric support 11 are articulated on printing equipment 900, and positioned at the inside of cavity 2010.Dielectric support 11 can have a handle, work as door closure After component 1 opens cavity 2010, the handle of dielectric support 11 can be lifted manually, print media 910 is held up.

Dielectric support 11 can also be associated with door body 10 and exist, and interrelational form can be that the mode of mechanical connection is closed Connection, for example, dielectric support 11 is pivotally connected or elastic connection is in door body 10, so that dielectric support 11 can The movement of door body 10 is followed to hold up print media 910.In this interrelational form, dielectric support 11 can be connected to servo-actuatedly Door body 10.
